Kevin bought a \( 7 \frac{2}{3} \) inches tall model of the Statue of Liberty. The scale used for the model was \( \frac{2}{3} \) inch \( =4 \) meters. What is the actual height, in melers, of the Statue of Liberty? Explain how you solved the question.

12. Angles \( A \) and \( B \) are a pair of alternate interior angles on a pair of parallel lines intersected by a transversal, and \( \angle A \) and \( \angle C \) are a pair of same-side interior angles on the same figure. If \( \mathrm{m} \angle B=30^{\circ} \), what is \( \mathrm{m} \angle C \) ?
